- Nowadays it is more and more common the existence of projects in which the involved participants are located at different sites, which might even be different countries. A project is an example of a collaborative effort. Another example of a collaborative effort is the development of a software system, which is seldom developed by a single social actor.
- The present invention describes a system and method to compute the complexity of the coordination of a given set of social actors when performing a collaborative effort. The present invention is directed to improving the method of managing a given set of social actors when performing a collaborative effort, using a system and a method to compute the complexity of the coordination of this effort.
- Aspects of the present invention are directed to a method of determining the complexity of a collaborative effort, comprising the steps of: receiving data by a processor, the data comprising identities of social actors or sets of social actors in the collaborative effort and storing the data in a repository accessible by the processor; defining nodes, by the processor, and associating the nodes with each of the social actors or with each of the sets of social actors in the collaborative effort to define nodes that represent each of the social actors or each of the sets of social actors; identifying, by the processor, one or more dimensions for each social actor or each of the sets of social actors; defining a coordination complexity (G) (calculated by the Formula (I) presented below), by the processor, and determining, for each dimension, a sum of a difference between every two of the nodes, multiplying the sum by a weight specific for that dimension, and adding each of the multiplied sums for each dimension.
- Formula (I) that computes the overall coordination complexity (G):
-
(G)=Σ↓(dimension=1)↑(dimension=N)[[((Σ↓i↑j[([Node])↓i])−[Node]↓j)]↓(Dimension N)*δ↓(Dimension N)] - In another aspect, the present invention provides a system configured to perform the presented method, including a specially programmed computer device having components configured to perform aspects of the method provided by the present invention.
- In one aspect, the invention provides a system of determining complexity of a collaborative effort comprising: a processor; a user interface functioning via the processor; and a repository accessible by the processor; wherein the processor is configured to: receive data comprising nodes, edges and weights; store the data in the repository; process the data by executing an algorithm or function stored in the repository; create a graph representation of the processed data that may be displayed on the user interface; determine a coordination complexity (G) according to a formula (I):
-
(G)=Σ↓(dimension=1)↑(dimension=N)[[((Σ↓i↑j[([Node])↓i])−[Node]↓j)]↓(Dimension N)*δ↓(Dimension N)]; - optionally, filter out the edges; determine the weights based on pre-determined information stored in the repository; and determine the nodes via social network metrics received by the processor.
-
FIG. 1 is a flowchart of the automatic method provided by the present invention. -
FIG. 2 is a system, including a computer device having components configured to perform aspects of the automatic method provided by the present invention. -
FIG. 3 presents an exemplary system diagram of various hardware components and other features, for use in accordance with aspects of the present invention; -
FIG. 4 is a block diagram of various exemplary system components, in accordance with aspects of the present invention. -
FIG. 5 is a graph provided by the system for the Example 1. - The present invention shall now be described in greater detail based on an example of execution represented in the drawing.
- The invention is useful for a collaborative effort to determine how complex, or simple, the collaborative effort will be, given the context of the social actors working on the collaborative effort.
- “Context” may mean different aspects of the collaborative effort to be carried out including:
- 1. The number of social actors involved in the collaborative effort;
- 2. The organizational membership of the social actors involved in the collaborative effort;
- 3. The geographical location of each social actor involved in the collaborative effort and the associated time-zone of these locations;
- 4. The languages spoken by each social actor involved in the collaborative effort;
- 5. The nationality of each social actor involved in the collaborative effort;
- 6. The previous experience in working together of the social actors involved in the collaborative effort;
- 7. The degree of interdependency among the tasks being carried out by each pair of social actors involved in the collaborative effort;
- 8. The availability of synchronous and asynchronous collaborative tools available to each social actor;
- 9. The mechanisms (including tools) available to each social actor that facilitate informal communication among the actors involved in the collaborative effort.
- Each one of the aspects above may be referred to as a dimension. Note that the values associated with each dimension are not important per se, because the system and method analyze the difference between the values of each dimension of any two social actors.
- In operation, for a given collaborative effort, the social actors are identified along with one or more of the above mentioned dimensions, and the dimensions of each social actor information are input into a specially-programmed computer system that implements this invention, e.g., based on the actions described herein, so that this system can compute the coordination complexity (G) of the analyzed collaborative effort. The resulting coordination complexity (G) is a numeric value, calculated by the Formula (I) presented below, that suggests the amount of coordinative work required by the social actors to perform the collaborative effort.
- Formula (I) that computes the overall coordination complexity (G):
-
(G)=Σ↓(dimension=1)↑(dimension=N)[[((Σ↓i↑j[([Node])↓i])−[Node]↓j)]↓(Dimension N)*δ↓(Dimension N)] - Based on the result, the processor may receive instructions to change aspects of the collaborative effort as a way of reducing the amount of coordinative work required to perform that effort. The processor may also receive instructions to automatically change aspects to reduce the amount of coordinative work. Examples of change include, adding collaborative tools to facilitate the coordination, replacing social actors, increasing the number of traveling by specific social actors, etc. More specifically, the processor can be instructed to change one or more of the social actors in the collaborative effort based on the coordination complexity (G) in order to reduce the value of the coordination complexity after a re-computation (i.e., a re-computed coordination complexity).
- In particular, referring to
FIGS. 1 and 2 , a system 200 may be configured to perform aspects of themethod 100 for the classification of the determining the complexity of a collaborative effort. - 1) The system 200 includes a
computer device 210, at 110 ofmethod 100, such as, for example, a laptop or tablet, wherein the data may be entered (nodes, edges and weights). - 2) The
computer device 210, at 120 ofmethod 100, processes the data, e.g., via adata processing component 209, which may be software and/or hardware executing one or more algorithm or function, such as, a specially-programmed computer system. - 3) Next, the
computer device 210, at 130 ofmethod 100, analyzes the data entered, via adata analysis component 208, e.g., creating a graph (Cormen, Leiserson and Rivest, 1990) representation that may include one or more nodes and one or more edges. This graph is an undirected graph (i.e., its nodes are connected by edges that are bidirectional) (Cormen, Leiserson and Rivest, 1990), each node represents either a person or a team that includes a set of actors and has a value assigned to each one of its different dimensions. For instance, an actor's value to the organizational membership dimension will indicate the team of which this actor is a member; if a node is a team, which includes a set of actors, then we use the most frequent value for a given dimension for the social actors located in this team. The edges are used to represent the difference between the dimensions of the collaborative effort of each node. For example, an edge between two nodes is used to indicate that there is a difference between the time-zones of these two nodes. In an aspect, the values of a given dimension for each node may not be important, but instead what is important is to represent that there is a difference between the nodes for a given dimension. This difference between the nodes for a given dimension is likely to create additional complexity to collaborative efforts, increasing the amount of necessary coordination. - 4) After the processing, analysis and computation of the data, filtering out the edges, optionally, may be performed, at 140 of
method 100. The process can be configured to filter out the edges automatically via anautomatic data component 206, or manually based on instructions received through the user interface. In the previous processing step, it is necessary to compare each pairs of nodes to find out whether there is a difference in their contexts, and therefore whether there is an edge between them. In other words, the previous approach assumes the coordination between all pairs of nodes is important. This step can be simplified because often, not all pairs of nodes might need to coordinate their work. For instance, in a software development project, nodes (which might indicate either software developers or teams) are more likely to engage in coordination efforts with other nodes they depend on or that depends on them. Therefore, a variation of the approach described in the previous step only takes into account the coordination complexity of a subset of the pairs of nodes. This subset might be determined manually or automatically using dependency analysis techniques including but not limited to (Podgurski and Clarke 1989), (Vieira and Richardson 2002), and (Stafford and Wolf 2001). The user of this system and method decides the approach to be used, automatic or manual. - 5) Next, the
computer device 210, at 150 ofmethod 100, computes the weights, via adata computing component 207 such as a processor, according to the approach selected by the user. Independently whether the full graph or a subset of the graph is taken into account in the previous step, an aspect of the method described in this invention includes an approach to compute the weights of each dimension. A possibility is to store data in a repository accessible by the processor (e.g, a memory device) containing the results of interviews (McCracken, 1998) with experts in the collaborative effort being analyzed to identify which weights they would assign for each dimension based on their previous experience with efforts in similar “contexts”. Interviews in this case could be conducted individually or in groups of experts using a focus group approach (Krueger and Casey, 2008) and then, the weights may be calculated either through the average weight attributed for each dimension or by reaching a consensus among the interviewee. Another approach is to use machine-learning techniques (e.g., Bayesian networks (Ben-Gal, 2007)) to compute the weights based on a database of previous collaborative efforts that took place in similar “contexts”. Finally, a third approach is to use simulation methods (Rubinstein and Kroese, 2007) to identify these weights based on a subset of the database of previous collaborative efforts that took place in similar “contexts”, and then evaluate and refine these values in the rest of the database. - 6) Then, the
computer device 210, at 160 ofmethod 100, computes the Coordination Complexity (G), viadata computing component 207. For each dimension, the summation of the differences between every two nodes of the graph is computed by summing the values of the edges. This summation indicates, for a given dimension, how different the social actors involved in the collaborative effort under analysis are. This sum is then multiplied by a weight (e.g., a weighting factor) that is specific for that dimension. Adding the results of the multiplication between the sum and the weight for all dimensions provides the overall coordination complexity of the effort. More specifically, the overall coordination complexity (G) is computed in the formula (I) represented below: -
(G)=Σ↓(dimension=1)↑(dimension=N)[[((Σ↓i↑j[([Node])↓i])−[Node]↓j)]↓(Dimension N)*δ↓(Dimension N)] - where G={V, E} such that V and E are finite sets that describe the different dimensions (context) of the collaborative effort to be carried out. V represents the set of vertices or nodes, and E represents the set of Edges. Therefore, “i” and “j” represent every two nodes in this graph.
- 7) It is important to note that in the formula (I) above presented, the weights are distributed in a way that the sum of all of the weights is 1. Because of that, the computed coordination complexity (G) does not need to be normalized since the sum of all weights is 1. In a variation of this invention, if the values of the weights do not need to sum to 1, then the overall coordination complexity (G) needs to normalized, i.e., the overall result must be divided by the sum of all the weights. Finally, the
computer device 210, at 170 ofmethod 100, may use social network analysis (Wasserman and Faust, 1994) to find out relevant nodes in the graph, viadata computing component 207. This is done by computing social network metrics in the graph representation of the collaborative effort. For instance, the degree centrality (Wasserman and Faust, 1994) metric can be computed to determine the node of the graph with the largest number of edges, and therefore, the one that will likely face the largest coordination effort. - The

FIG. 5 shows the Undirected Graph of the example provided, i.e., one embodiment of a coordination effort. - In this case, the nodes A, B, C, D, and E represent social actors involved in a collaborative effort. The edges connecting some of these nodes indicate that the social actors associated with the edges are different in one dimension of the context. The referred effort is to develop a project in Brazil, Belo Horizonte.
- A is an actor that speaks Portuguese and who lives in Belém, Brazil; B speaks Portuguese and lives in Sao Paulo, Brazil; C speaks English and lives in Belo Horizonte, Brazil; D speaks English and lives in Toronto, Canada; E speaks Portuguese and lives in Montreal, Canada. Table 1 provided below shows the nodes and the dimensions of each node of this example. Table 2 provided below illustrates the edges of this example indicating the reason why the edge exists between two nodes and the dimension in which the nodes are different. Note that, for this example, not all possible edges are represented in the graph.

Similarly, there are two edges from A to C, because these two social actors are located in different cities and speak different languages, which means they will require a greater effort to collaborate.
- The overall collaborative effort of this project is computed by calculating the summation of the result between the number of edges that exist in the graph for a given dimension (language, location, etc) multiplied by the weight of this dimension. As an example, having in mind the location of the project, the values of the edges and weights vary according to the distance to Belo Horizonte and the language, preferably Portuguese. The values of the edges for a given dimension represent the difference between the values of this same dimension for the nodes linked by this edge. More details will be presented below.

FIG. 5 , it is possible to compute the coordination complexity as described in Table 3. By computing the degree centrality (Wasserman and Faust, 1994) of each node in the graph it is also possible to identify that the node C is the one with the largest coordination effort, since it is the one with the largest degree centrality. For the user of this invention, this information can suggest that node C might need extra-time to conclude his/her tasks, or might want to use additional collaboration tools to facilitate his/her work, and so on. The decision about what needs to be done is left to the user of the invention, and is not included in the scope of this invention. - Although a preferred operational process has been described and illustrated, it is pointed out that alterations in this process are possible and executable, without digressing from the scope of the present invention, and the given example do not intend to limit the scope of this invention.
